Note 1:
Overtemperature limits are guaranteed by design and not production tested. Devices tested at +25

C only.
Note 2:
RESET2
asserts before

CC
goes below the threshold for all supply voltage and temperature ranges.
Note 3:
CSRT must be connected to either V

(for fixed
RESET2

adjustable

timeout period).
